Experimental study on injection characteristics of near/supercritical RP-3 aviation kerosene

  • 摘要:

    针对未来先进航空发动机的超临界燃油喷射混合需求,采用纹影系统对近临界和超临界RP-3航空煤油喷射进入静止大气中进行了试验研究,并结合RP-3航空煤油10组分替代物对近/超临界燃油喷射过程进行解析。研究表明:近/超临界燃油喷射会产生激波结构,并且在喷口附近有相变过程,但是近临界和超临界喷射无论是在整体射流结构抑或是近喷嘴处射流结构上都有着不同,与近临界喷射相比,超临界喷射在马赫盘内气相区/液相区更大,再液化距离更长;同时随着喷射温度的增加,马赫盘直径和纵向距离以及射流扩张角均会减小,而随着喷射压力的增加,马赫盘直径和纵向距离以及射流扩张角均会增加。
